PacificWild, a British Columbian environmental organization, has deployed a network of 6 hydrophones in waters along the northern coast of that province. This region of offshore islands and dramatic forested fjords is relatively wild, and quiet, especially as compared to the shipping-intensive region in southern BC around Vancouver Island and nearby Puget Sound in Washington State. But development proposals (including tar sands and other oil and gas ports) may mean up to 3000 supertankers per year will pass through these northern waters, bringing an expansion of the acoustic smog that already blankets most of the world’s oceans.

Ian McAllister of Pacific Wild stresses that “Most of the species that are acoustically sensitive rely on a quiet ocean in order to communicate, in order to forage, in order to survive here,” and notes that the hydrophone array will gather crucial baseline acoustic data that can help inform management decisions to be made in the next few years.
